IMPROVEMENT IN GLAZIERS TOOLS.

Specification forming part of Letters Patent N 0. 212,515, datedFebruary 18, 1879} application filed November 14, 1878.

To all whom it may concern:

Be it known that I, WILLIAM H. G. SAVAGE, of Kingston, in the Provinceof Ontario and Dominion of Canada, have invented a new and ImprovedGlaziers Tool, of which the following is a specification:

The object of this invention is to furnish glaziers and manufacturers ofpicture-frames and others a tool for holding and driving the sheet-metalpoints or brads into the frame for holding the glass or wooden back inplace.

It consists of a prismatic receptacle with a follower actuated by aspring, said receptacle being joined at right angles to a bar with atriangular opening in line with the receptacle, and on the opposite sideof the bar from the receptacle is made a longitudinal rabbet covered bya metallic plate, and into the socket thus formed a plunger isreciprocated, which drives the brads or points into the wood when theyhave been forced out into the socket.

In the accompanying drawings, Figure l is a plan of my improvement. Fig.2 is a side elevation of the same. Fig. 3 is a sectional detail of thereceptacle, and Fig. 4. is a modification of my improvement.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a plunger, provided with ahandle at one end, and having a longitudinal slot, 1), through which ispassed a set-screw, d, that enters the bar or plate B. A longitudinalrabbet, a, is made in bar B, extending its entire length, and theplunger moves freely in this rabbet, it being limited, however, in itsmovement by the screw (1, which likewise holds it in place.

At the lower end of the bar is screwed a metallic plate, f, covering therabbet, so that the plunger moves inside of it when reciprocated. Thebar B is likewise provided with a triangular opening under plate f, asshown by the dotted lines in Fig. 2. From this opening, on the oppositeside of the bar from plate f, extends at right angles the prismaticreceptacle or triangular trough O, the angles and sides of whichcoincide with the angles and sides of the opening in the ba-r B, fromwhich it extends. This trough is provided with ahinged or sliding door,as may be preferred, which completely covers it in.

Inside the trough is placed a spiral spring, 0, one end bearing againstthe end f of the trough, while the opposite end is provided with afollower, which bears against the last one of the triangular metallicpoints 9 placed in the receptacle. These points are placed in thetrough, commencing at the end Where it joins the bar B, and the springis retracted to make way for them. The action of the spring keeps thesepoints pressed up to the end of the receptacle, and the last one on theend opposite the spring bears against the inside of the plate f when theplunger is withdrawn, the space being sufficient to admit one only.

The operation of my device is as follows: The receptacle being filledwith the points and the trough closed in, the plunger is withdrawn asfar as it will go. The tool is then turned with the receptacle in anupright position, while the plate f bears upon the wooden back or pane,as the case may be, while the end of the bar B is placed against theside of the frame at the point where the metallic point is to be drivenin. The plunger is then driven in, and its end, coming in contact withthe base of the point, (which is toward it, as indicated by the dottedlines in Fig. 2,) drives it forward and into the side of the frame. Assoon as the plunger is drawn back the spring forces the points forward,and another takes the place of the one driven out by the plunger.

In this way great facility and rapidity in driving these points areobtained, and the trouble and time occupied in picking up the points andentering them into the Wood ready for the action of the hammeris-avoided.

In Fig. 4 a modification of the invention is shown. Here, at theopposite end of the trough G from the bar B, a socket, h, is provided,into which the spring is entered. By forcing the spring found easier toplace the points in the receptacle or cloth. This is likewise providedwith a hinged lid instead of a sliding one; but one or the other can beused indift'erently.

A hole, '6, is'made in one side of the trough 0, close up to the socketh. When the spring is pushed back preparatory to filling the trough withthe brads, a piece of wire is put through the hole so it will projectacross the end of the spring or follower and hold the spring back inback into this socket it will be the socket, thus enabling the workmanto employ both hands in filling the receptacle.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An improved .glaziers tool for driving brads tohold window-panes and wooden backs for pictures in the frame, and othersimilar purposes, consisting of the reciprocating plunger A, providedwith the slot 1), secured to plate or bar B, provided with plate f, incombination with receptacle 0, having spring 0 for forcing the brads orpoints out of the receptacle, whereby the points, being forced out ofthe receptacle against the inside of plate f,

are driven thence by the plunger A and en- WILLIAM HENRY GILES SAVAGE.
